Title:
ANTENNA DEVICE AND ANTENNA ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/110375
Kind Code:
A1
Abstract:
The present invention is provided with: a main reflection mirror (11); a sub-reflection mirror (12) including a plurality of sub-reflection mirror panels and having a reflection surface which faces a reflection surface of the main reflection mirror; and a primary radiator (13) for receiving radio waves reflected by the sub-reflection mirror (12). Sub-reflection mirror panel driving mechanisms coupled to the sub-reflection mirror panels are each finely driven. On the basis of change in reception electric field intensity of radio waves received by the primary radiator (13) when the sub-reflection mirror panel driving mechanisms are driven, a phase calculation unit (171) calculates relative phases of element electric field vectors respectively corresponding to the sub-reflection mirror panels, and determines positions of the sub-reflection mirror panels where phase distribution at an opening surface of the main reflection mirror (11) is minimized.
